Full 634 v2.0 feature set: This USB version retains the entire feature set of the original 634 v2.0:

  • The LCD material for the positive displays is FSTN (Film compensated Super Twisted Nematic) instead of STN. FSTN gives better contrast, faster response and makes an all-around more readable display.
  • The display as the ability to store a customized boot screen of your design in its EEPROM. All features of the display are controlled: characters displayed, user-definable characters, backlight setting, contrast setting, cursor position, cursor style, "wrap" setting, "scroll" setting, and even the scrolling marquee.
  • The CGROM is an enhanced version with many more useful characters: numeric superscripts, icons, mathematical symbols, some fractions, a great variety of arrows, many currency symbols, and more.
  • Large, easy to read characters: 7.3mm (0.287") character height
  • Available with bright, even, software adjustable LED backlighting or in a low-power reflective model
  • Software controlled contrast
  • "Gapless" horizontal bargraphs
  • Software controlled terminal style automatic scrolling and line wrapping
  • Unique "Scrolling Marquee" feature continuously scrolls a message across the display without host intervention.
  • Buffered communication
  • Large display area in a compact 130mm x 63mm (5.12" x 2.48")package
  • Thin:
    • Reflective is 15.9mm (0.626") including DB-9 connector
    • LED Backlit is 19.9mm (0.783") including DB-9 connector
    The USB converter board and its compact connector does not add to the overall thickness of the module.
  • Negative voltage for contrast generated on board
  • Available in a LCD drive bay kit, (see mounting bracket photos)
  • Available with serial interface
